Application led June 30, 1908. Serial No. 441,150.

. To all whom 'it 'may concern: v ,l l@Be it known that I, WILHELM SCHULZ, l citizen of the United States, residing at No. 1103 Crockett street, Houston, in the county 6. ofI-Iarris and State of Texas, have invented certain new and useful Improvements in Flexible Metallic Hose, of which thefollow 1n is a specification. 1

y. invention relates to new and useful improvements in flexible metal hose. The object of my invention is to provide a hose involving certain improvements-ion the device set forth in the Letters Patent issued to me June 11, 1907, Number 856,427.

Among the novel features are the provision of comparatively smooth joints or connections and the obviation of all i'iternal standards, levers 'and the like.

Finally the object of the invention is to provide a device of the characterdescribed that will be strong, durable and elicient, and simple and comparatively inexpensive toA produce, also one in which the several parts will not be liable to get out of working order. W'ith` the above and other objects in view, the invention has relation to certain novel features of construction and operation, an example of which is described in the specification and illustrated in the accompanying drawings, wherein: 'fi' Figure 1 is a side elevation of amodiied form of hose, Fig. 2 is a-longitudinal sectional view through one of the sections of the same, Fig. 3 is a longitudinal section of one of' the sections, Fig. 4 is a similar view of the corresponding section, Fi 5 is a plan' "view of-the coupling sleeve, an Fig. 6 is a sectional viewr of the same.

In the drawings the numerals 18 4and 19 designate a plurality of members or sections.

These sections are connected by thimbles 20 and suitable joints or couplings 21, some of which joints operate at right angles to the others. The sections being formed of metal,

' 4,5 it is obvious that a flexible hose movable in various directions is provided and it is further to be noted that any desired number of sections and joints may be used. In view of' the fact that the joints are all of substantially the same construction, a description of one will suflice for the fest. I, v

Section 18 is formed l,witha cylindrical couplingmember 22 having a round and grooved seat 23 adapted to Contact with the ground Seat24( of acoupling member' 25 formed on tle end; (if the section 19. A coupling sleeve 27 is ypassed snugly through the seat Q3 and has itslower end 28 reduced and screw threaded soas to be driven in the seat 24. This sleeve has a rounded and ground flange 29 engaging in the grooved portidn of the seat 23 and holding the members together, thusprevcnting leaking and permittin the sections to swing. For holding the s eeve against rotation a set-screw 30 is threaded through the, sleeve into the seat 24 as isshown .in Fig.,9', said scre\. lying at an angle and extending upwardly within the sleeve'. The upper end of the member 22 is closed by a cap nut 31 threaded therein, upon thel removal of which access may be had to the coupling sleeve and parts. It will be noted that the joints are disposed at right angles permitting movement in various directions and further that the sections 1S may be connected Aby the thimbles 20 as wellas the sections 19 and the hose connected as herein-before stated.

A metal hose constructed as herein set forth will not only becompact and practical but less liable to injury and disconnection by reason of the absence of the standards and levers and other? projections, beside beformation. .Y

That I claim,

In a flexible pipe joint, the combination with two fluid conducting coupling members having flat contacting faces, ofl a iange carried by one of said` coupling members, the inner face of said liange having an annular groove formed therein, a coupling sleeve threaded into the other of said coupling members and projecting into the first coupling member, said sleeve being formed with an outwardly projecting flangehaving a bead formed upon its under face, said bead conforming to the shape ot and lying within the grooveiof the flange otl the first named coupling member. and.y a locking screw which pierces the wall of saijil sleeve and enters the second coupling member to thereby bind said sleeve against inox'cincut with relation to said coupling .uicuibcfn the out\\'ardly proing of a more substantiall and permanent ject-ing iunge of the coupling sleeve extending from wall t0 wel] of the first named (coupling member and Suid screw lying at. :Ln angle und extending up\\'urd1y within the sleeve, :1nd u removable cup threaded Within the rst named Coupling member abovevsad sleeve.
